These products are designed to deliver reliable bonding performance across different substrates, structures, and application conditions. (https://en.crown.com.cn/Product_2/52.html)

EPT(Acrylic Foam Tape) – High-Shear Series

The EPT High-Shear Series delivers excellent shear strength and bonding performance, combined with outstanding weatherability and sealing properties. It effectively withstands vibration and impact, helping reduce the risk of bonded-component displacement for long-term, reliable bonding.

Designed for high-reliability bonding of automotive exterior components, the series is suitable for body claddings/rocker panels, emblems, B/C-pillar trims, radar brackets, shark fins, spoilers, and other industrial bonding applications requiring high performance.

EPT(Acrylic Foam Tape) – Rapid Wet-Out Series

The EPT Rapid Wet-Out Series features fast wet-out, enabling rapid and stable bonding to medium- and high-surface-energy substrates, while also providing good adhesion to low-surface-energy materials.

With high adhesion, high shear strength, excellent weatherability, and good sealing performance, the series is mainly used for bonding automotive display bezels, radar brackets, emblems, and other automotive components.

EPT(Acrylic Foam Tape) – High-Expansion Series

The EPT High-Expansion Series features a high-expansion foam structure with excellent softness, elasticity, and conformability. It effectively accommodates complex curves and interface variations while providing good impact resistance, weatherability, and sealing performance.

The series provides excellent adhesion to medium- and high-surface-energy substrates such as metal, painted surfaces, ABS, and PC, and is primarily used for automotive sealing-strip bonding.

EPT(Acrylic Foam Tape) – Low-Surface-Energy Series

The EPT Low-Surface-Energy Series is specially developed for bonding challenging low-surface-energy substrates, delivering reliable adhesion to a wide range of difficult-to-bond materials, particularly PP+EPDM composites.

The series also provides good shear strength, weatherability, and sealing performance, making it suitable for long-term bonding of automotive exterior components such as B/C-pillar trims and spoilers.

EPT(Acrylic Foam Tape) – High Initial Tack & Adhesion Series

The EPT High Initial Tack & Adhesion Series provides excellent initial tack and adhesion, enabling strong adhesion under low application pressure and within a short bonding time. This facilitates rapid positioning and assembly while improving production efficiency.

With high bonding strength and good weatherability, the series is primarily used for bonding automotive exterior components such as body claddings/rocker panels and B/C-pillar trims.

EPT(Acrylic Foam Tape) – High Pull-Strength Series

The EPT High Pull-Strength Series is an acrylic foam double-sided tape designed to deliver excellent normal pull strength and high shear strength, helping maintain durable and stable bonding performance.

Combined with excellent weatherability and sealing properties, the series provides reliable adhesion to substrates such as metal and glass and is primarily used for high-reliability emblem bonding.

From high-strength structural bonding to complex curved-surface applications, and from low-surface-energy substrates to high-reliability exterior component assembly, EPT (Acrylic Foam Tape) provides a versatile portfolio designed to meet diverse automotive bonding requirements across different materials, structures, and processing conditions.

Looking ahead, CROWN will continue to advance material, structural, and process innovations in EPT (Acrylic Foam Tape) in response to the trends toward lighter, smarter, and more advanced vehicles, delivering high-performance and reliable bonding solutions for automotive manufacturing and a wide range of industrial applications.
